Variation of the elastic constants of 2024-T351 Al under dynamic pressures

Commercial Manganin gauges were used as in-material gauges in planar shock experiments. The Hugoniot curve for 2024-T351 Al was determined in the 0–10 GPa range and was found to coincide with that of 2024-T4 Al given in the literature and measured by other techniques.

Zusammenfassung:Commercial Manganin gauges were used as in-material gauges in planar shock experiments. The Hugoniot curve for 2024-T351 Al was determined in the 0–10 GPa range and was found to coincide with that of 2024-T4 Al given in the literature and measured by other techniques. The longitudinal sound speed was determined as a function of stress and it was found that Poisson’s ratio decreases while shear modulus increases in this stress range.
